A commerative gold ingot from the first gold pour using our cyanide-free recovery method. The infrastructure for a processing plant that uses cyanidation typically costs $30 million, and is therefore, a barrier to entry for gold miners with smaller deposits that do not fit into the large-scale economies of gold production.
producing substances which can reduce the efficiency of gold leaching. Minerals that cause excessive consumption of cyanide are called cyanocides. Examples include copper, nickel, iron and sulphide minerals. If they are present in the ore, extra cyanide must be added which can add considerably to the cost of leaching the gold.
Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH In a ... Read more Skip to content Laboratory Testing Consulting & Engineering Process Equipment
Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent.

Process optimization and control are critical aspects of the gold leaching process to ensure efficient operation, maximize gold recovery, and minimize costs. Here are some key considerations for optimizing and controlling the gold leaching process: 1. Monitoring Key Parameters
Gold Leaching done in round vats, constructed of wood, concrete, or iron and steel. If wood is used it is covered by a coating of paraffin paint, or by a mixture of asphaltum and coal-tar. Concrete and brick vats are not now advocated owing to their great cost and less convenient working, and wooden vats suffer more than iron and steel …

Picture 4: Color test to confirm presence of gold In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction. Vats usually do not contain much internal equipment, such as agitators, baffles hence aeration is limited and therefore oxygen which is important for gold dissolution.
